Cooling Water Corrosion and Its Control:Part 1

Once-through cooling has become less common, as regulations have been enacted to protect aquatic creatures from impingement/entrainment and thermal hazards at plant intakes and discharges, respectively. Thus, cooling towers (or in an increasing number of cases air-cooled heat exchangers) increasingly are de rigueur at new facilities. The author began his career at a power plant with once-through cooling for turbine exhaust steam cooling and for other major auxiliary heat exchangers. Once-through cooling was a common choice for many plants in the last century, although cooling towers were certainly also very much a part of many designs. With once-through cooling, but perhaps even more pronounced with cooling tower-based systems, many possibilities exist for fouling and corrosion of cooling system equipment. Source: caledoniancables

Agorist Challenge: Fixing Flint Michigan's Poisoned Water

The government and institutions charged and trusted to ensure the residents of this Michigan city had safe drinking water already demonstrated criminal levels of negligence and corruption, causing the problem to begin with. A year on and the "solutions" presented have ranged from simply forcing residents to buy bottled water and unsustainable charity providing those bottles, to superficial, even deceptive measures like replacing home faucets instead of the miles of... US President Barack Obama declared a federal emergency in Flint over a year ago - meaning that the problem isn't just corrupt, negligent, and criminal politicians in Flint - but that the incompetence and impotence goes all the way to Washington.
